Outcome(s)

Primary Outcome

- Objective Response Rate (ORR) [ Time Frame: Up to Month 24 ]
ORR defined as percentage of participants with confirmed best overall response of Confirmed complete response (CR) and partial response (PR) per investigator review according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.

Secondary Outcome

- Duration of Response (DOR) [ Time Frame: Up to 24 Months ]
DOR is defined for participants achieving a confirmed CR+PR as the time from the initial response of CR+PR per investigator review according to RECIST 1.1 criteria to disease progression or death of any cause, whichever occurs earlier.
- Overall survival (OS) [ Time Frame: Up to 24 Months ]
Overall survival (OS) is defined as time from first study treatment to death due to any cause.
- Progression free survival (PFS) [ Time Frame: Up to 24 Months ]
Progression-free survival (PFS) is defined as time from first study treatment to a documented disease progression according to RECIST version 1.1, as determined by the investigator, or death due to any cause, whichever occurs earlier.

Key inclusion & exclusion criteria

• Age minimum: >= 18age old
• Age maximum: Not applicable
• Gender: Both

Include criteria

- Histologic malignant solid tumor diagnosis (World Health Organization [WHO] criteria).
- Measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.
- For Part 1 only - history of advanced solid tumor that has progressed on all standard of care therapy and are not amenable to surgical resection or other approved therapeutic options that have demonstrated clinical benefit.
- For Part 2 only - history of advanced non-squamous wtEGFR or mutEGFR or history of advanced squamous Non-Small Cell Lung Cancer (NSCLC) that have progressed after treatment with at least:
- Platinum-based chemotherapy and an immune checkpoint inhibitor and/or appropriate targeted therapy for an actionable gene alteration, if applicable, for non-squamous wtEGFR and squamous NSCLC (Parts 2i and 2iii).
- Platinum-based chemotherapy doublet and tyrosine kinase inhibitor(s) (TKI[s]) for non- squamous mutEGFR NSCLC (Part 2ii).
- Should have no more than 2 lines of prior cytotoxic chemotherapy excluding adjuvant therapy and must have advanced NSCLC that is not amenable to surgical resection or other approved therapeutic options that have demonstrated clinical benefit.
- For Part 3 only - history of advanced histopathologically or cytologically confirmed diagnosis of gastroesophageal adenocarcinoma/gastroesophagel junction adenocarcinoma (GEA) that has progressed after treatment with at least 1 prior cytotoxic chemotherapeutic regimen for locally advanced or metastatic disease and have not received more than 2 prior lines of cytotoxic chemotherapy regimens. Participants must have progressed on
- If applicable, an immune checkpoint inhibitor.
- If applicable, appropriate available therapies, including HER2-directed therapies.
- For Part 4 only - Participants with history of advanced histopathologically or cytologically confirmed colorectal cancer (CRC) that does not harbor the BRAF V600E mutation and are not dMMR+/MSI-Hi with progression on:
- A fluoropyrimidine (e.g., 5-fluorouracil or capecitabine).
- Oxaliplatin.
- Irinotecan.
- If applicable, anti-EGFR (including, but not limited to cetuximab or panitumumab).
- If applicable, anti-vascular endothelial growth factor (VEGF) monoclonal antibody (including but not limited to bevacizumab, ramucirumab, or aflibercept).
- If applicable, targeted therapy
- Participants who are considered ineligible for or are intolerant of standard therapy per investigator are eligible. Prior treatment with Lonsurf or Regorafenib is also acceptable.
- For Part 5 only - participants with advanced histologically or cytologically confirmed solid tumors characterized by MET amplification who are not amenable to surgical resection and who have disease progression after at least one prior systemic therapy and/or who have no satisfactory alternative treatment options. Participants who are intolerant to standard treatment are eligible.
- Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1.
- Laboratory values meeting the criteria outlined in the protocol.

Exclude criteria

- History of interstitial lung disease (ILD) or pneumonitis that required treatment with systemic steroids, nor any evidence of active ILD or pneumonitis.
- History of idiopathic pulmonary fibrosis, organizing pneumonia (e.g., bronchiolitis obliterans), drug-induced pneumonitis, or idiopathic pneumonitis.
- History of clinically significant, intercurrent lung-specific illnesses.
